参考答案
1．A 从句子“A star is born from dust and gas.”可知“恒星是从尘埃和气体诞生的。

2. B 从第一段最后一句和第二段可知短文简要介绍了star从诞生(are born)、长大(grow old)到死亡(die)的过程。

3. C 短文介绍了有关恒星的知识，短文第一句应该是问：你问过自己有关恒星的事吗？有关恒星的事不能“搬动”，也不能“看”，所以选C。

4. B 从句子“The ball gets very hot. Then it starts to give off light.”可知：恒星变热后才发光的。

5. A 从短文第二段，尤其是“The young star grows into a giant. Many years go by. The older star begins to get small again.”可知恒星会存在很长时间。
